FLYING-MACHINE.

Application filed December 16, 1915.

To all whom 'itmay concern:

Be it known that I, GEORG C. SCHLE, a citizen of the Republic of Switzerland, residing at Herisau, Switzerland, have invented certain new anduseful Improvements in Flying-Hachines; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to an improved mechanism t'or cross-stabilizing or balancing iying machines` which may be operated automatically or by hand, and whichv makes use oi the atmospheric influences, which are apt to injuriously atleet the vertical position ot the machine, in setting up counter-moments. allowing at the saine time the operator then wilfully to retain the position into which such lateral iniuences have tilted the machine. This is obtained by providing an upper and a lower stabilizer, to be called into service independently of one another` but preferably combined, when both stabilizers may be operated in conjunction or separately. In the lower balancing device either end ot' a cable is resiliently attached to opposite sides ot' the car, which latter. is suspended from the frame work with capability ot' oscillating in lateral direction only,

the cable heilig guided over fixed points disposed laterally outside of the axis of oscillation. rI`he upper balancing device comprises a pendulous lever, to the lower end of which are resiliently secured the ends of a cable which is guided over fixed points disposed laterally without the axis of oscillation of said lever and coperates with a drum, located in the oscillation axis of the lever and serving for operating special steadying'surfaces secured to the lateral wings. In case both of these stabilizers are provided on the same machine, provision may-be made whereby the driver can operate both mechanisms at will, and the pendulous lever and swinging car may be temporarily rigidly connected. o

In order to make my invention more read- Specicaton of Letters Patent.

ily understood, I will now describe it in detail with reference to the accompanying drawings, in which:

Figure 1 represents a side elevation,

Fig. 2 a front view,

Fig. 3 a fragmentary plan,

Fig. 4 part ofFig. 1, on an enlarged scale and partly in section,

Fig. 5 a detail in plan,

Fig. 6 a section on line A-B of Fig. 5,

Fig. 7 a section on line C-D of Fig. 5,

Figs. S and 9 respectively show diagrammatically and perspectively the cable layout.

The car 1 is suspended from the machine frame by the hangers 2, suitably secured in pairs to the car sides and forming ball bearings 3 at the upper converging ends. The inner bushes of these ball bearings are fixed on the shafts i, which latter are journaled with no axial play in bearing brackets 5 forming part of the body or frame 6. This arrangement allows of the carswaying to and fro in a cross-wise direction. T o take up the axial end-thrust there are provided converging braces 7, respectively secured to the rearmost hanger pair and forming at the top the bearing 8, which together with the thrust bearings 9 is supported on the shaft 10, which latter in turn is journaled with no relative axial displacement in the brackets 11 rigidly secured to the machine frame 6.

In a bearing standard 12 in the car 1 is journaled a shat't 13 to which are ixed the cable drum 14 of a cable 15 and' a sprocket 15". Several turns of the cable 15 are laid around this drum, and the two cable-ends are guided over pulleys 16, which are hung up on theniachine body laterally of the axis of oscillation of the car and somewhat above it, as shown in Fig. 2. The cable-ends then return to the car and are resiliently secured thereon, tor instance by mea-ns of spring-barrels 17 of well known type. If atnone point of the cable a pull is exerted, the spring will be put under tension and part of the cable rolled up in the respective barrel will unwind. If, on the other hand, the normal pull on one end oi the cable is eased, then the spring will again draw-in part of the previously withdrawn cable.

Within easy reach of the driver are proioo i vided bearing blocks 18 one of which journals the shalt 19 direct, while the other rotatably houses the sleeve 20, which in turn journals the shaft 19 (Fig. 6). To the sleeve 20, which, as it were, constitutes a shaft by itself, is rigidly secured a hand-wheel 21 and a chain-wheel 22, which latter is operatii ely connected with the sprocketv 15a by the .chain 23. The hub of the handwheel 21- constitutes a toothed wheel 24. The bearing 18 next to the toothed wheel 24 has av diskshaped enlargement 25, provided with a solitary notch equal in dimensions tothe gap between each two teeth of, the Wheel 24. Into this notch and any tooth gap can engage simultaneously the wide blade 27 ofia. double-armed lever 29, which is rotatable about the pin 28 supported by the bearing 18, and to the other end of which is linked one end of a draw rod 30, whose other end is pivotally secured to the hand lever 31, which in turn is rotatably secured with its lower end to a stud 32 extending from the car l, as clearly shown in Fig. 7. A leaf spring 33 is secured to the car and snaps with a pin 34 behind the lever 31 when the latter assumes its outermost position when laid over in the direction of the arrow.

If the handwheel 21 is for instance rotated toward the right, which .obviously can only be done if the blade 27 iS not in the notch 26, the "right-hand part of the cable 15`Will be wound on drum 14 from out of the respective spring barrel 17, since the cable drum 14 is forced by reason of the chain drive 22, 23, 15a to follow the movement of the handwheel 21;

The left-hand part of the cable correspondingly slackens and the slack is drawn into the respective spring barrel 17. If now the lever 31 is laid over as indicated by the arrow in Fig. 7, the blade27 will take into the notch 26 of bearing 18 and also in between two teeth in the wheel 24. This interconnects the car with the machine frame, since now the cable, drum 14 can no longer be rotated and the cable mechanism cannot be operated one way orthe other. This coupling between car and machine body or frame can obviously be effected at any desired relative angle. Thepin 34 of the leaf spring 33 locks the lever 31 and prevents its return, with the result thatthe blade 27 is securely retained in its locking position until the driver pulls back the spring 33, which trees the lever 31 and allows it to swing back into theinoperative position.

On the shaft 19 (Figs. 5 and 6) is fixed a handwh'eel 35 and a cable drum 36, around which latter several turns of a cable 38 are passed. Coming up from below one portion 38:l of this cable passes over a pulley 39 whose axis coincides with the axis of oscillation of the car in the constructional example shown. 'It would suffice if this pulley 39 as well as an adjacent pulley 40, were located near the oscillation axis, and, again thesel two pulleys could also be rotatably secured to the underside of the one frame arIn or strut 5. The portion 38b of the cable passes from pulley 39 (Figs. 2, 4 and 8) over a pulley 43 which is rotatably journaled on one end of a double-armed bracket 41 fast on the body 6. The succeeding port1on`38c of the cable then extends toward a spring barrel 42, where the cable end is elastically secured to the housed spring. The other cable portion 38d ascending trom the drum 36 passes over the said pulley 40, then as portion 38f (Fig. S) over a pulley 44, which is supported on the other end ofthe bracket arm 41, and finally as portion 38g into the spring barrel 45. These two spring barrels are secured to the rear of a pendulous lever g5 46, Whose axis et' oscillation coincides with that of the car. For this ourpose there is provided a smaller shaft 47, freelyrotatable with one end in the short rigid" shaft 4 (Fig. 4) and in the respective bearing bracket. To this shaft 47 is rigidly secured the lever 46 as at 48, and the one end of this shaft extends freely into the cable drum 49, into whose other end, in turn loosely extends a pintle or gudgeon rigidly held in a bracket bearing 51.

To the front face of the lever 46 are secured the two spring barrels 52 and 53 and a cable 54 is passed in several turns about the already referred to drum 49. The pOr- 100 tion 54a (Fig. 8) of the cable passes over a pulley 55 journaled coaxiallyuof the pulley 43, and then as portion 54" to the spring drum 52. The other cable portion 54c passes over the pulley 56, which is journaled col105 axially of the pulley 44, and the portion 54-i finally extends to the spring barrel 53.

Two more cables 57 and 58 (Fig. 9) are v passed in several turns around thel drum 49, their ends respectively extending to the 110 right and left and their lay-out being substantially identical. The portions 57a and 57 of the cable 57 pass over a guide pulley 59 to the cable pulley 60, which later is rotatably journaled in the hinge axis 61 of the 115 stabilizing planes 62 of the wing 63 and connected thereto b v cables 64. The end ofthe section 57" is carried around the pulley 60 a certain distance and then secured thereon. over the guide pulley 65, tl'nough the wing 63, 'over the guide pulley (36 locatedabove the wing (Fig. 3) and finally. as section 57d, to the cable pulley 60, where its end is Secured in the manner of the other cable end, 125 as described above. The arrangement of the l other cable 58 is identical to the one just described with reference to cable 57, the

lcable being lguided over guide pulleys 67,

The cable section 573 passes in turn hinge axis 61a of the stabilizing plane 62 and connected thereto by means of the cables G-La.

From the above it is clear that by the oscillation of the lever 4G, which serves as pendulum, the stabilizing planes G2 and 62a are automatically controlled, but can also be actuated at the will of the driver by manipulation of the handwheel 35.

For the purposes ot' combining the crossstabilization by reason of the lateral oscillations of the lar with the actuation of the stabilizing planes by the oscillations of the lever IG, the following arrangement has been provided. To the front hangers 2 of the car is rigidly secured a bearing T() y(Fig. l) provided with two cheeks T2 and T3, which are hinged `together as at 71, forming a clamp. To the cheek 72 is secured a spindle 7l, which is threaded at the farther end and carries a correspondingly threaded handwheel 75. Between this handwheel and the clamp cheek 73 is interposed a sleeve, loosely surrounding the spindle Tl and intended to transmit the thrust of the handwheel, on the latter being rotated toward the right, to the cheek 73, which then causes the two cheeks to exert a clamping action. .Turning back the handwheel, obviously, will release the clamp again. In between these two clamp cheeks extends the lower portion of a disk 76 the upper part of which is rigidly secured to the short shaft l? and thus partakes of the movements of the lever 46. If theclamp 72, T3 is locked on the disk T6, it will be seen that the upper and the lower stabilizing devices must operate in unison.

By means of the handwhecls 2l, S5, 'T5

and the hand-lever 31 quite a variation ofl cross-stabilizing maneuvers may be executed either' manually or automatically. If. for instance, the handwheel 35 is turned toward the right, the rope section 38 will be wound up onto the drum 36 and the section 38 will be correspondingly unwound therefrom, with the result, that the lever lt will'be tilted toward the right. If, however. the disk 76 is clamped in the clamp T2 by the operations of the wheel 75, which is possible no matter what the relative angular position between lever and car, then the lever i6, now rigidly securedto the car. must partake of the latters oscillations. The handwheel 35 and the drum 86 do not rotate. since the pulleys 39 and 40 are situated in or near the axis of oscillation of the car.

In order to ilnpart a high degree of rigidness to the entire machine, despite the pendulous suspension of the car, there is provided a bridge or trcstle for bracingand stiffening the wing frame. Above the middle wing supporting tube 7T, which is removably secured to the body by means of flanges T8, there is provided a two-part yoke tube 79, which is connected with its outer ends to the cross-tube 77 as at 80, then ascends toward the center where the two sections are joined by flanges S1. Vertical brace tubes 82 are interposed at suitable intervals between the members T9 and 7T. The beam 79 is further braced against a forward wing supporting member 83 and against a rear ard wing member Sl by ties or stays S5. The wings, thus, together' with the wing trestle, form a rigid trellis structure. Every pulley is preferably provided with flanges or side wheelsl to prevent the cable from slipping olf.
